The Lowdown

Alright folks, Rusty here, and I’ve been staring at the charts for Jaconé, and let me tell you, it’s a mixed bag. We’ve got a real slow start, then a solid pulse of energy rolling in, but you gotta pick your moments.

Right now, there’s basically nothing doing. The first few days are limp and ordinary. Wednesday the 19th has some tiny 4ft waves from the ENE with a weak 7-second period, and the combined energy is only 171 – that’s barely a ripple. The wind is cross-off, so it’s clean, but there’s just no power. Thursday the 20th is even smaller, with 3ft to 3ft waves. It’s surfable, but it’s a real struggle to get excited.

Then we hit a gap. Friday the 21st morning starts to look a bit more promising – the swell jumps to 6ft from the ENE, period stretches to 8 seconds, and the combined energy shoots up to 544. The wind is a light cross-off, so it’s clean. That’s a decent window, but it gets blown out hard by the afternoon when a strong onshore SW wind kicks in at 30 km/h. Saturday the 22nd is a write-off with onshore winds and messy, poor conditions.

Now, here’s where it gets interesting. The real standout is Monday the 24th. That morning, we’ve got 7ft of swell from the south, with a nice 13-second period. The combined energy is a whopping 1450 – that’s serious power. The wind is a light cross-off from the ESE, keeping it clean. This is excellent surf for experienced surfers, but heads up: the afternoon gets too big, with 10ft swell predicted, which is too much for this break. So hit the early session.

Tuesday the 25th morning is another cracker. Offshore NE wind at 20 km/h, with 8ft swell from the south at 14 seconds. The energy is 3029 – that’s a proper groundswell. This is for experts only, and the long period means it’ll be grinding, so watch for those sets. The water temp is about 22°, which is pretty normal for this time of year.

Wednesday the 26th morning is a treat – glassy conditions with a light W wind, 6ft S swell at 13 seconds, and 1101 energy. That’s clean, powerful, and beautiful. The rest of the week settles down, with smaller but still clean waves through the 27th and 28th, and then it fades out into weak, ordinary surf by the end of the month and into early September.

So, bottom line: don’t waste your time this week. The best window is Monday the 24th morning, with Tuesday the 25th morning and Wednesday the 26th morning as the next best. If you’re experienced and you want to get wired, that’s your call.

Rusty.

Information about the Jaconé Surf forecast

The above surf forecast table for Jaconé provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Jaconé can be found by selecting the local surf guide option on the grey menu. Our Jaconé surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period. If you surf the same spot (Jaconé) regularly then make a mental note of the wave energy from the surf forecast table each time you go. Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).

Further information to help with frequently asked questions about our surf forecast for Jaconé may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.

Jacone is 14 km (9 miles) from the city of Saquarema. If you plan a holiday in Rio de Janeiro, look for hotels and other accommodation in Saquarema. Saquarema has rooms for a wide range of budgets as well as car hire and transport links.
